摘要
双宾短语是一种特殊的语言现象,为了使计算机能够理解并处理双宾短语,该文从语法和语义两个层面对双宾短语进行了分析,基于概念知识树知识表示模型建立了双宾短语的语义表达模型;并提出一种双宾短语分析算法,实现了从双宾短语到其语义表达模型的自动转换。双宾短语分析算法采用自顶向下和自底向上相结合的方法,自顶向下用于对双宾短语的语法成分进行划分,获得构成双宾短语的双宾动词成分、间接宾语成分和直接宾语成分;自底向上用于使用基于概念知识树的短语分析推理算法对双宾短语中的这三种成分分别进行分析,获得对应的语义表达;最后,利用三种成分的语义分析结果构建双宾短语完整的语义表达。该文从权威文献和语法词典中选取了122个双宾动词,对这些双宾动词构成的209个短语进行了分析,分析的正确率为90.43%,证明了该文提出的双宾短语分析算法和语义表达模型的有效性。
This paper analyzes the double-object phrase which is a special linguistic phenomenon from the syntactic and semantic perspective,and presents a semantic double-object expressive model based on Conceptual Knowledge Tree（CKT）.Moreover,this paper proposes a method for analyzing the double-object phrases,which can automatically translate them into the semantic expressive model.It firstly,in a top-down style,classifies the syntactic parts of a double-object phrase into three parts-double-object verb,direct object and indirect object.And then,in a bottom-up style,it uses CKT to do inferences on these three parts and get their semantic expressions.Experiment on a dataset consisting of 122double-object verbs and 209phrases selected from authoritative literatures and grammar dictionaries reveals an accuracy 90.43%.
